Re: [Getfem-users] Help regarding Eigenvalue problems

[Iago Barbeiro]

Hi Arvind,

I never really worked with the Schrodinger's equation and I'm just a beginner with getfem, but I've already dealt with some eigen-problems involving the Navier-Stokes equation. 
I would say that GetFem is the right tool for building your matrices in the FEM way with its very good flexibility, but then you will need to learn how to use an eigen-solver, such as ARPACK. You can even link it to your Getfem code.
Guys, please correct me with I said something  wrong!!  (thanks) 
Good luck
Iago

Hi

I need to solve Schrodinger's equation $ H \psi = E \psi $ on a 2D domain. I could not find any mention of
the capabilities getfem++ has regarding the solution of eigenvalue problems using FEM.

Does anyone have any idea as to how I should go about solving this problem? Stretching my luck a little too far,
does anyone have experience solving schrodingers's equation using getfem?

Look forward to your replies.

Best wishes
Arvind Ajoy
